When copper oxide is heated with hydrogen, copper metal and water are formed. What happens to the copper oxide in this reaction?

Correct option is C

The correct answer is (c) Reduced.
In the reaction where copper oxide (CuO) is heated with hydrogen (H₂), the chemical equation is:
CuO+H2→Cu+H2O
In this process:
· Copper oxide (CuO) is reduced to copper (Cu). Reduction refers to the loss of oxygen, and in this case, copper oxide loses its oxygen atoms to form copper metal.
· Hydrogen (H₂) is oxidized to form water (H₂O) because it gains oxygen.
Thus, copper oxide undergoes reduction in this reaction, as it loses oxygen. Hydrogen, on the other hand, is oxidized as it gains oxygen.
Information Booster:
· Reduction: A process in which a substance loses oxygen or gains electrons. Here, copper oxide is reduced.
· Oxidation: A process where a substance gains oxygen or loses electrons. Hydrogen is oxidized in this reaction.
· This is a typical redox reaction, where reduction and oxidation happen simultaneously. Copper oxide is reduced, and hydrogen acts as the reducing agent.
· Water (H₂O) is the product formed due to the oxidation of hydrogen.
